Titles in this collection include:

Part of the Salem Science collection. Heavily illustrated and detailed, and completely up-to-date, The Solar System provides essential coverage on all major aspects of Earth's solar system, from every feature of the major planets to their satellites, small bodies and cosmological context. All essays from the previous edition have been fully expanded and revised to include additional knowledge gained from recent interplanetary missions, from the Darwin mission to the latest Mars rovers and orbiters.

Part of the Salem Science collection. The topic of global warming has become a major issue over the past few years. More and more, people are learning about environmental sciences and the possible planetary effects of our everyday actions. Encyclopedia of Global Warming provides complete, authoritative coverage of the science, policy and social issues surrounding global warming and climate change. The essays in this set address a broad range of topics, from scientific concepts to social issues to current laws, organizations, people, and much more.

Part of the Salem Science collection, this new addresses one of the fastest-growing subjects in academic curricula—the forensic sciences, which are also known as criminalistics. Over the past decade, there has been an explosion of both public and academic interest in the application of scientific techniques to investigations of crime. Television audiences have developed a seemingly insatiable appetite for shows such as CSI: Crime Scene Investigation and Cold Case that go into the minutiae of how forensic techniques are used to solve crimes. The emphasis in such shows tends to be on crimes of violence, particularly murder. However, although forensic sciences do indeed play a major role in homicide investigations, they are also applied to a multitude of other kinds of investigations, ranging from simple accidents and arson to war crimes and writing instrument analysis—all subjects studied in academic courses on forensic science and criminal justice.

This three-volume set introduces students to issues surrounding both current energy sources and alternative energy options. While there is significant discussion of the non-renewable resources now used to meet the majority of the world's energy needs (oil, coal and natural gas), the primary focus of the set is on newer options to meet the ever-growing demand.

Provides a wide range of scientific, historical and cultural information about the animal world. Covers careers in the animal sciences in addition to biological concepts, the history of zoology, biographies of scientists, and ethical issues such as the practice of animal experimentation. Includes illustrations, sidebars, charts, a glossary, bibliographies, filmographies and the addresses of institutions devoted to the protection and study of wild and domesticated animals.

This guide presents extensive data on the habitats and ecosystems of more than 1,200 species identified as endangered or threatened by the U.S. Fish and Wildlife service. Entries include introductory information with an image of the species; a summary section detailing information on each species; a concluding summary of recovery efforts; and a bibliography of contacts for further information.

Explains biological concepts and explores related fields as well as the history of biological science. Discusses critical issues such as embryogenesis and commercial applications of research in biology and addresses ethical issues. Provides information on careers in biology and contains color illustrations, sidebars, bibliographies, timelines, charts, and a glossary.

Provides descriptions of household and high-interest products, step-by-step descriptions of manufacturing processes, and sidebars with additional information. Covers for each entry: why there was a need, who invented it, how it is made, what it is made of, and how it works. Includes photographs, illustrations and line drawings, and a glossary of definitions.

Offers information on the ways in which different chemical elements combine to form commonly-used chemical compounds, such as water, ammonia, and aspirin. Defines what a chemical compound actually is and the difference between organic and inorganic compounds, as well as providing definitions of acids, bases, salts, oxides, and coordination compounds. Features a general historical overview of major discoveries and the notable scientists who made them.
